recreational water quality standard Articles

Microbial safety of recreational water is one of the major human public health issues in developing countries. Three water bodies, the Tbilisi Sea, Kumisi and Lisi lakes, in the South Caucasus region near Tbilisi, Georgia, were monitored in 2006–2009 to determine microbiological quality using standard methods. Microbial pollution indicators were determined in parallel with phytoplankton ...

ABSTRACTThis investigation was sponsored by the Texas Water Conservation Association (TWCA) with support from the Association of Metropolitan Sewerage Agencies (AMSA) and the Texas Association of Metropolitan Sewerage Agencies (TAMSA). The study was conducted by seven Texas river authorities in association with Dr. William W. Walker, Jr., Ph.D., and Alan Plummer Associates, Inc. (APAI). Its ...

The objectives of this study were to examine the seasonal changes in the risk of gastrointestinal (GI) illness of beachgoers in the tropics, to compare the association between GI illness and water quality using various indicator organisms, and to study other beach health hazards. A prospective cohort study during two seasonal periods (summer and autumn) was conducted in a beach surrounded by ...

ABSTRACTLenexa’s Rain to Recreation Program has a three-fold mission (1) reduce flooding, (2) improve water quality, preserve the environment and open space and (3) provide for new recreational and educational opportunities in the undeveloped portion of the city. To support the Program’s watershed based “systems” approach to stormwater management a diversified ...

Monitoring recreational waters for fecal contamination by standard methodologies involves culturing indicator bacteria, such as fecal coliforms and enterococci. Delayed reporting of microbial water quality parameters increases the likelihood of public exposure to pathogens of fecal origin, making the development of rapid methods important for ...

A prospective cohort epidemiological pilot study was performed at three tropical beaches with point- and non-point-sources of fecal pollution to characterize the risk of illness among swimmers and non-swimmers. There was an increased risk of illness in swimmers as compared to non-swimmers, even when waters met current microbial standards for recreational water quality. Illnesses included ...

Standards for bacteriological recreational water quality in Puerto Rico are those proposed by US EPA. The standard for primary contact recreational use has both single-sample limits and running- average threshold limits based on historical data developed for the specific site. La Parguera is the site of a Special Marine Reserve and counts among its unusual habitats a phosphorescent bay, important ...

Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...

Saudi Arabia’s Standards on Ambient Water Quality seek to establish a framework to enable sustainable management of ambient water quality; protect the water supply and natural aquatic environment; and provide a basis for the restoration of waters used for recreational, agricultural, industrial, potable, and ecological ...

The new ASTM Water Portal provides a single access point to standards and related information about ASTM International’s diverse committees working to protect and monitor this vital global resource. Clean and safe water is the underpinning of the quality of life for people around the world. Global economies depend on water, whether it’s to support the manufacturing of goods ...

Water quality has been a central theme in a redevelopment project that began with the creation of the Cardiff Bay Development Corporation in April 1987. This article will examine the role that water quality has played in the remarkable transformation that has taken place in Cardiff and explain how monitoring technology has developed to the stage whereby any person, anywhere in the world, can view ...

The water quality of seafronts and beaches of Mumbai is under pressure and deteriorating due to discharge of partially treated sewage and wastewater through point and nonpoint sources. The objective of the study was to assess the water quality and to correlate physico-chemical and bacteriological parameters for establishing relationship, association and dependence on each other. The water quality ...

ABSTRACTSection 101 of the Clean Water Act requires recreational activities to be protected when and where they occur. States, which have adopted a wide variety of strategies to meet this obligation, have one or more formal use classifications to recognize different types of recreational activities. Most states have developed narrative or numeric water quality criteria to limit pathogen pollution ...

The microbiological quality of waters in estuaries determines their acceptability for recreational uses. Microbiological contamination often results from urban wastewater discharges or non-point source pollution (manure spreading), and can cause bathing zones to be closed. European regulations (EC/7/2006) have proposed standards (500 E. coli/100 ml) for the acceptability areas for bathing. In ...

Water is critical for life and is integral to virtually all economic activities, including food and industrial production. Not only is clean water a prerequisite for human health and well-being, it provides for aquatic habitats that support healthy freshwater ecosystems. A range of pollutants including nutrients, biocides, pathogenic micro-organisms, industrial and household chemicals, metals and ...

Background 'Duemmer' is a shallow lake in the south-west of Lower Saxony; through the lake flows the river 'Hunte'. The catchment area spans 426 km2. With a surface of 12.4 km2 and an average depth of 1.1 m there is a water volume of approx. 14 million m3. Large parts of the lakeside are a nature reserve and the lake is a popular local recreation area. The lake suffers from strong nutrient ...

This study evaluated the effects of farming activities on the quality of deep well water in Southern Chile. In this area, the use of fertilisers is becoming more widespread and the accumulation and poor management of cattle slurry and silage sub-products increases the risk of contamination. The study was carried out in the province of Osorno, where rainfall occurs all year round (maximum in ...

Water is an increasingly scarce resource for much of the World's population. Global warming, an increasing world population and generally increasing incomes mean the demand for water is likely to rise further. If current trends continue, we will use 40% more water by 2024 than we do now. In industrialised countries much of the water used for non-potable purposes such as industrial applications, ...
